Researchers have discovered that frozen video-language models inherently encode an "evidence-readiness" signal, indicating whether sufficient evidence for a question has arrived in the video stream. This signal is linearly readable across multiple models and is question-conditioned, meaning it changes based on the query. The encoded readiness outperforms traditional uncertainty estimators and can be leveraged to create a new answer-timing policy called Readiness Gating, which improves accuracy without significant computational cost.
